Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What property of water molecules causes surface tension and cohesion?
A
Covalent bonds
B
Bent shape
C
All non-metal atoms
D
Polarity
Explanation: 

Detailed explanation-1: -Water’s high surface tension is due to the hydrogen bonding in water molecules.

Detailed explanation-2: -The water molecules attract one another due to the water’s polar property. The hydrogen ends, which are positive in comparison to the negative ends of the oxygen cause water to “stick” together. This is why there is surface tension and takes a certain amount of energy to break these intermolecular bonds.

Detailed explanation-3: -As a result of water’s polarity, each water molecule attracts other water molecules because of the opposite charges between them, forming hydrogen bonds. Water also attracts, or is attracted to, other polar molecules and ions, including many biomolecules, such as sugars, nucleic acids, and some amino acids.

Detailed explanation-4: -The polarity of water molecules allows liquid water to act as a “universal solvent, ‘’ able to dissolve many ionic and polar covalent compounds. The polarity of water molecules also results in strong hydrogen bonds that give rise to phenomena such as surface tension, adhesion, and cohesion.
